SOLUTION: In the endoscope, the end part of the optical fiber bundle 4 is securely inserted into a cylindrical fiber bundle cap 5 made of a metal and a cover lens 7 is fastened on the tip face of a metallic fiber receiving frame body 6 with a through hole so formed therein as to get the fiber bundle cap 5 securely inserted into it. The fiber bundle cap 5 and the cover lens 7 are joined airtight onto the fiber receiving frame body 6 with respective inorganic materials.
